(iii)

Septic tanks and septic tank drainfields are prohibited in the setback area of (ii) above.

B.

The perennial stream corridors outside a seven-mile radius upstream of a governmentally owned public drinking water supply intake or water supply reservoir are protected by the following criteria:

The site plan shall be certified by a Georgia Registered Engineer or Surveyor. Each site plan submitted shall include the following:

1.

A site plan drawn to a scale and showing all planned improvements including width, depth, and length of all existing and proposed structures, roads, or accessways, watercourses, drainageways, water, wastewater, and stormwater facilities, utility installations, and parking areas.

2.

Location, dimensions, an area of all impervious surfaces, both existing and proposed, on the site.

3.

The orientation and distance from the boundaries of the proposed site to the nearest bank of an affected perennial stream or body of water.

4.

Elevations of the site and adjacent lands within 200 feet of the site at contour intervals of no greater than five feet.

1.

If construction described in the development permit has not commenced within 12 months from the date of issuance, the permit shall expire.

All development activities or site work conducted after approval of the site plan shall conform to the specifications of said site plan. Significant changes to the site plan that would alter the amount and velocity of stormwater runoff from the site, increase the amount of impervious surface within the development, alter the overall density of development, result in a considerable increase in the amount of excavation, fill, or removal of vegetation during construction, or otherwise result in an alteration of the overall appearance of the development as proposed, can be amended only with the approval of the community development director. Minor changes such as realignment of streets or minor alterations to drainage structures and other infrastructure to meet unexpected conditions are exempted from this requirement.
